Visual Studio 2012 终极新依赖图错误 [英] visual studio 2012 ultimate new dependency graph error

问题描述

使用 Visual Studio 2012 Ultimate 每次创建新的依赖图时都会收到此错误:

working with visual studio 2012 ultimate everytime i create a new dependency graph i get this error :

Unable to connect to the specified database.

An exception occurred attempting to connect to a database using the following connection string:
Data Source=(LocalDB)\v11.0;AttachDbFilename=;Initial Catalog=master;
Integrated Security=True;Enlist=False;
Asynchronous Processing=True;MultipleActiveResultSets=True;Connect Timeout=30.

Check that the specified SQL Server instance exists and the service is running.

我的解决方案得到正确构建，我的连接字符串是这样的:

my solution get build properly and my connection string is something like this :

<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=.;Initial Catalog=JewelryStore;Integrated Security=SSPI;" providerName="System.Data.SqlClient" />
</connectionStrings>

这里有什么问题?

推荐答案

您的问题很可能是您的 localDB 实例的问题:

Your issue is likely a problem with your localDB instance at:

%localappdata%\Microsoft\Microsoft SQL Server Local DB\Instances\v11.0

我遇到了同样的问题，因为当我安装 VS12 时，我的计算机不在域中，而且我最近将它加入了域，而我的用户帐户没有访问 SQL DB 的权限.
为了解决我跑的问题

I had the same problem because when I installed VS12 my computer was not in a domain and I recently joined it to a domain and my user account does not have permissions to the SQL DB.
To fix the issue I ran

sqllocaldb stop "v11.0" -k
sqllocaldb delete "v11.0"
sqllocaldb create "v11.0" 
sqllocaldb start "v11.0"

然后我重新启动了 VS 2012，我的本地数据库现在可以使用，并且现在创建了依赖关系图

I then restarted VS 2012 and my local DB is now usable and the Dependency Graph is now created
